Really nice! I don't see this type of games really often, especially this well executed. Cool sound design, fluent gamepla and an excellent atmosphere. Although a completely different style. The type of game made me think of a game called "We Want YOU".
One thing I don't like is the scrolling screen-by-screen. It's a personal preference maybe, but I think if you keep the player sort-of-centered, it plays more fluently. Also less jittery when switching back and forth.
And one REALLY small improvement I suggest: Make the SPACE also restart a game, so you don't have to reach for the mouse at all.
